Hex Nut Factory introduces how to judge the strength of hexagon bolts?

Generally speaking, hex bolts are ordinary bolts of 4.8 grade, and those over 8.8 can be called strength hex bolts. Many steel structure construction occasions require the use of high-strength bolts to meet practical applications.

Especially for high-strength bolts, the correct judgment method must be mastered when judging. Generally, high-strength bolts refer to the two parameters of "friction" and "pre-tightening". But many people are prone to misunderstandings.

Many people think that the material grade is above 8.8, then the bolt must be high strength. In fact, the main criterion for high-strength hexagonal bolts is not the strength of the material itself, but its stress form. As for its stress form, it is simply bolts. The pre-tightening force that can be applied, and the main criterion for high-strength hexagonal bolts, is not the strength of the material itself, but the form of stress, which is simply what the bolt can do.

Many people in the industry believe that strength is determined by high rigidity, safety, and resistance to damage. In fact, the strength of bolts is actually related to its load-bearing capacity.

High-strength hexagon bolts should have the characteristics of large joint stiffness and small elastic deformation, so even under combined load, even if the number of bolts does not change, they are still suitable for high-strength working environments.

Through the above introduction, Hex Head Zinc Bolts Manufacturers hopes that you can simply refer to the content of this article in future use.
